Co-registration:
1 . Definition / Objectives:
Co-registration provides a user who has just completed a qualification form from a major advertiser (after an e-mailing campaign to build a database) with the possibility to subscribe to another advertiser's newsletter (or subscription / club / private sale, etc.).

2 . Advantages:
- Decide on the number of leads to get (depending on your budget)
- Create a database with opt-in prospects / customers
- Save the cost of creating a collection kit
- Quick start
- Get all the new applicant data (name / last name, mailing address, occupation, date of birth, city...), and receive them in a week
- The Viral Kit: Up to 1 out of 2 of the registered contacts invite other contacts to receive communications (trackbacks)
